MAN/MACHINE INTERFACE FOR CONTROLLING AT LEAST TWO FUNCTIONS OF A MOTOR VEHICLE
First Claim
1. A human/machine interface to control at least two functions of a motor vehicle, the human/machine interface comprising:
- a capacitive touch pad that comprises an array of electrically charged electrodes, the capacitive touch pad being configured to receive a command for at least one function;
a haptic feedback device configured to provide feedback to the user of the human/machine interface on recognition of the command; and
a control device configured to receive, from the touch pad, a signal representative of a command from the user on said touch pad, the signal being linked to the disturbance of the electrostatic field generated by the array of electrodes upon a command from the user on the touch pad,the control device being configured to determine the function to be activated when the level of the signal received is greater than or equal to a threshold value as a function of the number of electrodes of the array of electrodes of the capacitive touch pad for which the level of the signal is greater than or equal to said threshold value.

Abstract
The invention relates to a man/machine interface (10) that can be used to control at least two functions of a motor vehicle, said man/machine interface comprising: a capacitive touch pad (20) including an array of electrically charged electrodes, and configured to receive a command for at least two functions; a haptic feedback device (40) configured to supply feedback to the user of the man/machine interface as acknowledgement of the command; and a control device (30) configured to receive a signal from the touch pad that is representative of a command from the user on the touch pad, said signal being linked to the disturbance in the electrostatic field generated by the army of electrodes (50) at the time of a command from the user on the touch pad. The control device is configured to determine the function to be activated when the level of the signal received is greater than or equal to a threshold value according to the number of electrodes in the electrode array of the capacitive touch pad for which the level of the signal is greater than or equal to said threshold value.
